Overview
The Texas Instruments SN74AVC4T234ZSUR is a 4-bit, dual-supply non-inverting voltage level translation device. This component is part of the Advanced Very-low-voltage CMOS (AVC) family, designed to support mixed-mode signal operation and voltage translation between different voltage levels. The device features two separate configurable power-supply rails, enabling asynchronous communication between B-port inputs and A-port outputs. This makes it suitable for a wide range of applications, including personal electronics, industrial, enterprise, and telecom sectors.
